I'm Rh negative. Whats that mean and should I be worried?

Stop worrying. about 15% of people are rh negative. Being a female if you are pregnant you will get a shot of Rhogam at 28 weeks and after delivery if the baby is rh positive to prevent problems with a future pregnancy. I am rh negative and got both shots each pregnancy since both of my kids were rh positive,
Stop worrying. You and about 15% of other folks lack the D antigen on your red cells. If your unborn child gets D from Dad, it can cause troubles for the next pregnancy if your physician isn't alert. Hopefully that won't be a probelm. Relax.
